landlock: Report the effective signal number
The signal-scope denial callback identifies its target but not the
effective signal. This loses permission-probe signal zero and makes the
file-owner hook's zero sentinel ambiguous.
Append an int signal argument to the typed-BPF callback. Preserve sig,
including zero, in hook_task_kill(). In hook_file_send_sigiotask(),
translate signum zero to SIGIO at the producer, where its meaning is
known.
Carry the effective signal and target domain ID in a private,
stack-backed context consumed synchronously. This requires no allocation
or task reference in the interrupt-capable file-owner path. Gate this
context and the remaining scope-only domain IDs with CONFIG_TRACEPOINTS.
Keep the tracefs record and audit output unchanged.

landlock: Report the actual ptrace tracer
The ptrace denial callback identifies only the tracee. Current is the
tracer during hook_ptrace_access_check(), but it is the tracee during
PTRACE_TRACEME, where the parent is the actual tracer. A consumer
therefore cannot infer both parties from the existing arguments.
Append the actual tracer task to the typed-BPF callback: current for
hook_ptrace_access_check() and parent for hook_ptrace_traceme(). Carry
it with the tracee domain ID in a private ptrace context. Both hooks
keep the selected tasks alive through synchronous dispatch, so no extra
task reference is needed.
Keep the tracefs record unchanged. The new context is available only to
typed BPF, while same_exec continues to describe the tracer that owns
the denying policy.

landlock: Fix network denial trace context
Network denial events report source and destination ports reconstructed
from audit data. Their zero values are ambiguous, and neither identifies
the complete endpoint that Landlock checked.
Carry the checked sockaddr and its signed length in a private trace-only
context. For an enabled event, validate the length and copy only the
initialized prefix into zeroed local storage. This prevents a typed BPF
program from reading uninitialized bytes while exposing the socket
family, socket, address, and length.
Replace the source and destination trace-record fields with one signed
port derived from the checked address. A value of -1 means that no port
was checked, zero is a valid port, and positive values use host
endianness. Bind blockers select the bind address; connect and send
blockers select the destination.

landlock: Fix rule tracepoint context
Name each event after the identity it reports. Add-rule events describe UAPI rule insertion, so rename them after LANDLOCK_RULE_PATH_BENEATH and LANDLOCK_RULE_NET_PORT. Check-rule events describe matches in internal rule trees, so rename them after LANDLOCK_KEY_INODE and LANDLOCK_KEY_NET_PORT. This remains accurate if multiple UAPI rule types share one lookup and stored rule. Keep denial event names based on filesystem and network families because they describe final access decisions. Use u64 for growable access masks passed by value to add-rule and check-rule typed BTF callbacks. CO-RE can relocate pointer-reached fields, but it cannot widen a scalar callback slot declared by a BPF program. Keep native access_mask_t for internal state and trace records. For add-rule callbacks, report the normalized per-call contribution passed to landlock_insert_rule() and expose the complete validated flags value. Put the ruleset and flags first as a common invocation prefix. This distinguishes duplicate and effective-zero additions without recovering arguments from saved syscall registers.

landlock: Fix filesystem denial blocker reporting
Filesystem topology denials are rendered with an empty blockers value
because their blocker is identified by the request type instead of an
access mask.
Introduce the private struct landlock_blockers to carry the request type
and final missing access mask to filesystem and network denial
tracepoints. Copy both members into named trace-record fields, then use
the type to print change_topology for topology denials while preserving
symbolic access masks for ordinary denials.
The request type lets typed BPF consumers distinguish topology denials
from access denials. Keeping the native access mask in a pointer-reached
field also lets CO-RE adjust existing programs' load width if
access_mask_t grows.

landlock: Fix tracepoint fixed-width type names
The new Landlock tracepoints use UAPI-prefixed __u32 and __u64 names for callback arguments and record fields, including internal IDs that are not Landlock UAPI values. Typed BPF consumers see callback typedef names through BTF. Use the kernel u32 and u64 aliases before release so the tracepoint contract does not present internal values as Landlock UAPI types. This changes BTF-visible typedef spelling but not integer widths, calling conventions, tracefs formats, or record layouts.

tracing fixes for 7.3:
- Don't destroy user event fields when removal fails
User event fields are destroyed before the event is removed from
visibility. But that can fail leaving the still visible event with no
fields. Move the destroying of the fields to after the event is
successfully removed from visibility.
- Initialize function graph state is fork before calling copy_exec_state()
For non-CLONE_VM forks, copy_exec_state() allocates a new task_exec_state.
If that allocation fails, ftrace_graph_exit_task() will free the tasks
ret_stack pointer. Since that pointer is still using the parent's
ret_stack, it mistakenly frees the parent's pointer too.
Call ftrace_graph_init() on the task first which will NULL out the new
tasks's ret_stack and if the copy fails, it will not free anything.
- Remove FGRAPH_MAX_INDEX
The macro FGRAPH_MAX_INDEX was added but never used. Remove it.
- Save ent_size in function graph printing of nested functions
The function graph tracer needs to look at the next event to see if the
next event is the return of the current function entry. If it is, it
prints a single line:
ktime_get();
Otherwise it prints it like a nested function:
tick_nohz_irq_exit() {
ktime_get();
kcpustat_irq_exit();
}
In order to look at the next event, it must save the current event so that
it has the information to print from it. It saves the event in the
iterator descriptor called "ent". What it doesn't save is the ent_size of
the event which is now used to know if the function graph arguments are to
be printed. The peek doesn't save the size so the size used happens to be
that of the size of the last event that was seen.
Save the entry event size in the iterator descriptor so that the correct
size is used.
- Fix several errors with freeing data in the histogram code
The histogram code had a lot of leaked or or incorrect accounting when
failures happen. Correct them.
- Fix histogram regression of .percent and .graph modifiers
Up until 6.3 histogram values could have "percent" or "graph" modifiers
that changed how they were printed. But a change that added restricting
histograms values from being strings, stack traces and other modifiers
inadvertently prevented them from using the percent and graph modifiers,
which were legal use cases for values.
Put back the percent and graph modifiers.
- Fix various typos in the comments
- Set the trace_clock before initializing a histogram with clock argument
The histogram API allows the user to specific which trace clock to use via
a "clock=" string. The histogram is set up first before the clock is
checked. If the passed in clock is not valid, it exits without fully
fixing up the histogram leaving it on the list and a use-after-free can
trigger.
Update the clock argument first and if it fails then exit gracefully
before the histogram trigger is placed on any lists.
- Restore :mod: trailer after parsing in ftrace_set_clr_event
The function ftrace_set_clr_event() modifies the parse string and needs to
put it back to what was passed in. It searches for ":mod:" via a strsep()
but fails to put back the first ':' in the string.
Add back the ':' in the passed in string.
- Take trace_array reference when opening a tracer options file
The options files are dynamically created and some tracers add their own
options. When a tracer adds their own list of options, the trace_array
holding them has an array to hold the list of options for each tracer.
This array increases in size via a krealloc(), and the new entry gets a
newly allocated array to hold the options of the new tracer being added.
The element in each entry of the tracer's option array holds a pointer
back to the trace_array, a pointer to the tracer it is associated to, a
pointer to the flags of the option.
The issue is that these arrays are freed when the trace_array is freed
when its instance it represents is removed from the instances directory.
There's a race that an open of one of these options files can happen when
the instance is being removed.
Add a new helper function to be called by the open function of the options
file to iterate all existing trace_arrays under a lock and find the one
that has the given option element in one of it's tracer arrays. If found,
then update the associated trace_array's reference counter to keep it from
being freed. If not found, have the open call return -ENODEV.
- Disable interrupts when acquiring the lock in rb_wake_up_waiters()
The function rb_wake_up_waiters() assumes it will be called in interrupt
context and does not disable irqs when taking cpu_buffer->reader_lock,
which can be called in hard interrupt context. The issue is in PREEMPT_RT,
this function is called in thread context leaving this lock open to a
deadlock.
Take the lock with interrupts disabled.
- Use rcu_assign_pointer() for tmp_ops filter hash
The tmp_ops used in update_ftrace_direct_mod() assigns its filter_hash
field directly, but that field is annotated as __rcu and sparse complains.
Assign it with rcu_assign_pointer()
- Fix use-after-free in enable_trigger_private_data_free()
The trace_event_call is accessed through the event_trigger_data's
trace_event_file pointer to put the trace_event_call on freeing. The issue
is that the trace_event_file data may have been freed already causing a
use-after-free. Add a field to the event_trigger_data that points directly
to the trace_event_call so that it can decrement its reference directly
without needing to go through the trace_event_file.
- Fix accounting of buffer data remote headers
trace_buffer_desc_size() and trace_remote_alloc_buffer() undercount the
number of pages is needed for the asked for size as it doesn't take into
account the meta data on each page. Add a helper function to do the
calculation properly and use that in these functions.
- Catch nr_page_va overflow in ring_buffer_desc sizing
The number of pages per remote ring buffer is capped by
ring_buffer_desc::nr_page_va (32 bits). A buffer_size large enough to
overflow that field would silently allocate a descriptor smaller than what
was asked for.
- Do not resize the subbuf order if any per_cpu buffer is disabled
The mmapping of ring buffers disables resizing the subbuffers, but it is
done per-cpu whereas the subbuf size change is done for all the per_cpu
buffers under the buffer->mutex. It could change the size of some while
the mapping is happening on others. Have the resize of the subbuf order
check all the per_cpu buffers under the lock to see if any of them is
disabled before starting and causing an inconsistency between buffers that
are being mapped.

wifi: mt76: mt792x: fix NULL dereference in ACPI SAR init during probe
Some laptops carry a MediaTek power table in their firmware, and the driver reads it to set a transmit limit for each frequency range. It only fills in the ranges themselves when it registers the device. The startup step that does this existed already, but it never programmed anything. Two recent commits made it run a regulatory update instead, which sets the limits on the way through, long before registration. As a result, on a machine that has the table the driver reads through an empty pointer and the interface never appears: BUG: kernel NULL pointer dereference, address: 0000000000000004 RIP: 0010:mt792x_init_acpi_sar_power Call Trace: mt7921_set_tx_sar_pwr mt7921_mcu_regd_update mt7921_regd_update mt7921_run_firmware mt7921e_mcu_init mt7921_init_work Skip it when the ranges are missing.

ring-buffer: Check resize_disabled before publishing the new subbuf order
ring_buffer_subbuf_order_set() stores the new order and only then walks
the CPUs, returning -EBUSY if any of them has resizing disabled. A user
mapped buffer has resizing disabled, and __rb_map_vma() reads
buffer->subbuf_order without buffer->mutex, so an mmap of an already
mapped CPU racing the failing order change sizes the mapping with the
new order and inserts pages past the sub-buffer into the VMA.
Check the CPUs before storing the new order.

Bootconfig fixes for v7.3-rc3
- bootconfig: Fix integer overflow and truncation vulnerabilities in size checks
. tools/bootconfig: Fix integer overflow and truncation in size checks.
Fix size check bypasses caused by integer overflow and truncation
when parsing initrd or standalone bootconfig files, preventing
buffer overflow and out-of-bounds writes in the userspace tool.
. bootconfig: Fix integer overflow in initrd size check.
Fix pointer arithmetic wrap-around in get_boot_config_from_initrd()
when handling crafted huge size values, preventing fatal kernel
page faults during early boot.

First round of Kbuild fixes for 7.3
- kbuild: don't delete in-flight filechk temporaries in asm-headers
A rule for generating header files was changed from using make
$(wildcard) fnglob to 'find' instead; as 'find' finds "hidden" files
by default, temporary files from Kbuild's 'filechk', used for
generating asm header files, may get deleted and break header file
generating.

tracing: Don't dereference trace_event_file in deferred trigger free
The enable_event trigger defers trace_event_put_ref() to the
trigger free kthread, but the trace_event_file can already be freed
when the instance is removed.
Keep the trace_event_call directly in enable_trigger_data so the
deferred free does not access the freed trace_event_file.

The assert, initially added on 7.3-rc2 just makes the problem explicit but is not the cause. Another highlight is a missed lock/unlock mutex in the xfs healthmonitor which was causing lockdeps warnings. Besides those two, this also contains a myriad of fixes for random bugs found by LLM tools in the healthmon, scrub and online repair. A few bug fixes for zoned xfs are also included. This also includes an accounting fix for our buffer slab cache where the memory payload associated to each object was not being properly accounted for. The remaining of the patches are a few lock context annotations added and/or fixed. They are mostly disabled by now, but still worth fixing before we get them enabled.

Pull erofs updates from Gao Xiang:
"The most impactful fix here is to disable LZ4 rolling decompression
for now.
AWS folks recently found their systems could get corrupted data with
some rare, specific LZ4 datasets, and after a deeper analysis, I found
the root cause is that there could be uncontrolled backward memory
copies in the current LZ4 implementation and it breaks the assumption
of the rolling decompression optimization, since the kernel LZ4
codebase is out of our control and it needs more time to plan how to
do next, so disable LZ4 rolling decompression for now to ensure data
correctness for real production on these rare cases first. The
technical details also see the corresponding commit.
Other changes are random minor fixes.
Summary:
- Disable LZ4 rolling decompression for now due to the uncontrolled
LZ4 implementation
- Fix missing sysfs feature entry for xattr prefixes
- Fix invalid LZMA decoders on resize failure
- Rearrange the inode_share cache key to avoid potential collisions
- Fix erofs_bread() when fsoffset is used on sub-page-block EROFS
filesystems"

RISC-V updates for v7.3-rc3
- Revert a bad fix, likely LLM-generated, in the pointer masking code
that confused the RISC-V hardware pointer masking implementation
with the Linux kernel tagged address feature
- Fix unexpected faults caused by kprobe instruction slot writes when
!CONFIG_STRICT_MODULE_RWX
- Fix unexpected faults on minimal configurations during runtime code
patching on !CONFIG_STRICT_MODULE_RWX systems
- Fix a misplaced variable clear causing incorrect reuse of previous
values in the RISC-V hardware feature probing code
- Fix two bugs in the PMU SBI perf code on rv32: use BIT_ULL rather
than BIT on 64-bit masks; and use a bitmap rather than an unsigned
long on a quantity that can exceed 32 bits
And a few miscellaneous cleanups:
- Avoid a potential dereference-before-NULL-pointer-check bug in the
PMU SBI perf driver
- Simplify the rv32 bug table code by using
CONFIG_GENERIC_BUG_RELATIVE_POINTERS (following x86 and PPC)
- Report the RISC-V standard ISA extensions Z[v]fhmin when support is
claimed for the superset RISC-V standard ISA extensions Z[v]fh; and
simplify our FPU test code to only check for the presence of the D
extension
- Use an existing kernel string helper in place of some open-coded
code in kernel/usercfi.c
- Fix some yamllint issues in the RISC-V DT bindings for CPUs
- Convert one use of __ASSEMBLY__ to __ASSEMBLER__ that snuck into the
RISC-V CFI selftest code
- Update the translation for the simplified Chinese translation of the
RISC-V kernel patch acceptance policy

ring-buffer: Acquire the lock with irqsave in rb_wake_up_waiters()
rb_wake_up_waiters() is a irq_work callback which is initialized with
init_irq_work(). As such it will be invoked in thread context on
PREEMPT_RT. Invoking the callback in IRQ context on PREEMPT_RT is not an
option due its usage of wake_up_all(). Since this callback may run in
thread context, it needs to acquire ring_buffer_per_cpu::reader_lock with
disabling interrupts and may not assume that they are disabled.
Use raw_spinlock_irqsave() to acquire ring_buffer_per_cpu::reader_lock.
